Murayama Oshima-Tsumugi is a tough and high-quality fabric woven in Musashi-Murayama City, Tokyo, and has been designated as an Intangible Cultural Asset of Tokyo.

It is said that this fabric was first woven in the mid-Edo period. It is made by combining the cotton Murayama-kongasuri and the silk Sunagawa-futo-ori techniques. In the 1920s, this was further adapted with the addition of crisscross splashed cotton threads and became one of the main products of Oshima-tsumugi.

Murayama Oshima-tsumugi has been woven using the original Murayama and Sunagawa village looms since the mid-Taisho period. The warp and weft threads are dyed separately, and there is no difference between the front and back sides of the cloth.

Over the years, the relentless efforts of the pioneering craftspeople eventually paid off, as testified in the high quality and toughness of this fabric.

In 1975, this fabric was designated by the Minister of International Trade and Industry as a Traditional Handicraft.
